You are going from one city to another city, your watch can be connected to a computer before you begin, you select the cities that you have to go to at certain hours.. and time will autochange.

Or it uses GPS to auto-auto-change.

The U.S. atomic clock, and similar radio signals are already being broadcast and used by devices such as this http://www.valcoelectronics.com/oregon/rm323a.htm

A watch version does exist, but I could not find a link to it. You press a button and it searches for the nearest update location.

Broadcast frequency is typically in the 80 to 100kHz band (yes kilo-hertz) and bit-rate is a low 10 to 30bps. Microsoft is actually considering riding ads on this system that will allow things like fridge magnets that periodically show different products.
